Attorney Pam Keith, whose low-budget 2016 bid for U.S. Senate got nearly as many primary votes as Alan Grayson‘s high-profile campaign, has formed an exploratory committee for a potential run for the U.S. House seat of Rep. Brian Mast, R-Palm City.

“I have announced an exploratory committee to run against Mast, and if the support is there, I will. So far, the response has been over-the-moon positive,” Keith said in a text message this morning. She said Mast’s vote Thursday for a health care overhaul supported by President Donald Trump “most certainly did not endear him to many.”

Keith, who served in the U.S. Navy Judge Advocate General’s Corps and then worked as an attorney for Juno Beach-based NextEra Energy, raised and spent about $250,000 last year on a Democratic Senate campaign that got 15.4 percent of the vote. Former Rep. and liberal celebrity Grayson spent about $5 million and got 17.7 percent in a primary that former Rep. Patrick Murphy easily won with 58.9 percent. Murphy went on to lose in the general election against Republican Sen. Marco Rubio.
